A Boeing Dreamliner is held in Tokyo after problem with power supply

Problem is fourth mechanical incident for a Dreamliner in 10 days

On Monday, issue with brake indicator diverted plane

Boeing: "We know it will continue to receive heightened attention."

An All Nippon Airways 787 Dreamliner was held in Tokyo after a mechanical problem, the fourth such incident for Dreamliners in 10 days.

The plane was delayed Thursday after a cockpit message indicated a problem with the power supply to its air-conditioning system.

More than 100 passengers who were supposed to fly to Frankfurt departed on a different plane eight hours after the scheduled departure time, ANA said.

Earlier this week, a Denver-bound United Airlines Dreamliner was diverted back to Houston after a problem with its brake indicator.

A week before, two United Dreamliners made unscheduled landings.

A flight from Denver to Tokyo was diverted to Seattle because of an indicated problem with its oil filter.
